ILLUMINATED ELECTRIC POSTER DEVICE.

Specication of Letters Patent.

Application led. March 19, 1917. Serial No. 155,694.

-BLA1R L. DoBsoN, citizens of the United States, residing at St. Joseph,in the county of Buchanan and State of Missouri, have invented certainnew and useful Improvements in Illuminated Electric Poster Devices, ofwhich thefollowing is a specification.

The object of 4our invention is to provide a clock which may be used todisplay advertising, either outdoors or indoors, the advertising beingpla-ced on a sectional ribbon and displayed as it slowly moves upward infront of a cabinet. The clock is also adapted to the display of astationary sheet of advertising placed immediately back of a section ofCelluloid, or other transparent iieXible substance inserted in theribbon.

We accomplish our object by the mechanism illustrated in theaccompanying drawings, in which:

Figure 1 is a front view of the clock and cabinet showing a blank for atransparent advertising sheet through a glass panel of the clock cabinetdoor; y

Fig. 2 is a side sectional view of the clock case and the interiorconstruction of the device showingthe motor, the method of powertransmission, the lengths of sectional advertising ribbon with a methodof using a maximum and a minimum length, a drive roller, a gravitytension roller and its chan nel guides, a plurality of rollers and theiradjustments, a plurality of flanges on the rollers, supports for` astationary advertising sheet, a wiring and lighting system andc0nnections, the arrangement of a translucent glass border around thecabinet door, a side interi-or view of a removable head which containsthe clock compartment, clock movement and adjustable bracket, atranslucent glass dial, a weatherproof glass face and a side view of theremovable front lto the base of the cabinet.

Fig. 3 is a front view showing the drive roller, the tension roller, itsweight and a section of its guides, an adjustable roller and itsadjustments to guide the ribbon and a portion of the ribbon, alsoportions of duplicate narrow belts with spacing connections, and flangesnear the ends of the rollers which touch the back of the ribbon, alsoportions of duplicate narrow belts with spacing connections, and flangesnear the ends of the rollers which touch the back ofy the ribbon K.

Fig. 4 is a view of the inside of the front door of the cabinet showingthe illuminating system and reflectors, the wiring connections and atranslucent glass border and a clear glass panel in the cabinet door.

Fig. 5 is a plan View of the lower rollers showing the motive power,said translucent glass border and the illuminating system, and flangesnear the ends of the rollers which touch the back of the ribbon K.

Fig. 6 is a wire mesh cloth, metal hooks on the ends of two sections ofthe ribbon showing the method of connecting the sectiens, and

Fig. 7 is a detail drawing of the ribbon guide and the rolleradjustment.

And Fig. 8 is a view similar to Fig. 2, showing a modification thereofin the 1hreading of the minimum amount of rib- Similar letters refer tocorresponding parts throughout the several views, the letter Aindicating the clock cabinet and B the clock. B1 indicates a clockmovement supported in cabinet A by anadjustable bracket C which isfastened at the sides of a dust-proof clock compartment D; thiscompartment is fastened to the roof of the cabinet and has a hinged doorD1. l)2 represents three thumb screws by means of which the clockmovement B1 is adjusted to any angle or position on bracket C and islocked rigidly in place by means of an auxiliary bracket attachment D3which is also fastened at the sides of compartment D.

D4 is a translucent glass dial in front ofwhich a removable,weather-proof, clear glass face D5 is placed, making the clockaccessible.l DG is a pane of glass which admits artificial light fromthe lighting system immediately below for the purpose of illuminatingthe translucent glass dial Dt. We preferably use `a clock which iselectrically wound and regulated. D7V is a removable head and containsthe clock B which is supported by pillars E E, which pillars areprovided with a base E1 having a removable front E2 having fastenings ee. F indicates a motor, G a drive roller and H H a plurality of pulleys.H1 H1 represent flexible transmission belts. I I represent suitableelectrical wiring, and J J are rollers f or carrying the ribbon. K is asectlon of ribstrips placed on the sides of tlie cabinet to form achannel at the ends of the tension roller Land its weight L1 enablingthem to move in proper alinement. Through the mediumlof said tensionVVroller we are enfabled to .use a'ribbon of varying lengths;

the ribbon maybe threaded in various ways.

"f The diagram in Fig. 2 indicates the method of threading the maximumamount of ribbon K; In using the minimum amount of vribbon. wepreferably thread the same inthe following manner 'from front of driveroller 'G to front and overupper roller J1 down to front and undertension roller L, up to front and over roller J 2, down back of rollerJ3, front andl down over J4, down back of and connecting under rollerGr, as shown in M M are adl Fig. 8 by lines marked K1K1. justablebearings uponv which the axles of adjustable.v roller J1 rest. M1M1are/flat metal strips hinged at their back ends and uponk whichadjustable bearings M M rest. 'M2M2 are thumb screws upon the heads ofwhich the movable ends of the flat metal strips M1M1 rest, therebyenabling thumb VVVscrews vM2M2 to raise or lower either end of bon K; TT are cross rods located at the top andpbottom and' immediately back ofthefrontsection of ribbon K to support a stationary sign or poster, (notshown). 40
